Hi Boaz, Just download the file using your standard browser mechanism. When I ctrl-click on the link "kyte-doolittle_hydrophobicity.cxc" in this page: <https://rbvi.ucsf.edu/chimerax/docs/user/preferences.html#startup> ...when viewed in Firefox on Mac, I get a menu that includes "Save link as..." Choosing that brings up a little dialog that I use to save the file (without changing the name, but you can change it if you keep the cxc part) to my desired download location. On other platforms or different browsers it might be slightly different how to get the context menu with the choice to save the file, but should be similar. Or since it is a plain text file, like you said, you can also view contents and then paste them as plain text in a text-editor to create your own cxc file. However it is usually easy just to save the file from the browser as described above. I hope this helps, Elaine ----- Elaine C.

Hi, You give a nice example of adding the kyte-doolittle_hydrophobicity.cxc to the custom_presets folder that I created, but where can I find this file? Or, should I paste the content of the file which is opened by pressing the link in the user guide into a file by this name ( I doubt it but nevertheless suggest it as a possibility). Excuse my naive question, please. Thanks, Boaz
